Transformation between Modes
This activity book offers two primary play modes: Sit & Play (flat) and Stand & Cruise (upright). To switch between modes, locate the central hinge mechanism.

Operating Modes
Sit & Play Mode
In this mode, the activity book lies flat, providing a comfortable and accessible play surface for babies who are sitting up. Children can interact with the various activities on both sides of the open book, exploring textures, shapes, and sounds at their own pace.
